Moonshotai

AISDK provides first-class support for Moonshotai with fully typed model APIs. Model capabilities are enforced at compile time using Rust's type system. This prevents model capability mismatches and guarantees the selected model is valid for the task (e.g. tool calling).

Installation

Enable the Moonshotai provider feature:

cargo add aisdk --features moonshotai

This installs AISDK with the Moonshotai provider enabled. Once you have enabled the Moonshotai provider, you can use all aisdk features with it.

Create a Provider Instance

To create a provider instance, call Moonshotai::model_name(), where model_name is the Moonshotai model you want to use. Model names are exposed as snake-case methods.

use aisdk::providers::Moonshotai;

let moonshotai = Moonshotai::kimi_k2_0711_preview();

This initializes the provider with:

Model: "kimi-k2-0711-preview"
API key from environment (if set with MOONSHOT_API_KEY)
Moonshotai's default base URL (https://api.moonshot.ai/v1)

Basic Text Generation

Example using LanguageModelRequest for text generation.

use aisdk::{
    core::LanguageModelRequest,
    providers::Moonshotai,
};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {

    let moonshotai = Moonshotai::kimi_k2_0711_preview();

    let response = LanguageModelRequest::builder()
        .model(moonshotai)
        .prompt("Write a short poem about Rust.")
        .build()
        .generate_text()
        .await?;

    println!("Response text: {:?}", response.text());
    Ok(())
}

Provider Settings

You can customize provider configuration using Moonshotai::builder()

API Key

let moonshotai = Moonshotai::<KimiK20711Preview>::builder()
    .api_key("your-api-key")
    .build()?;

If not specified, AISDK uses the MOONSHOT_API_KEY environment variable.

Base URL

Useful when routing through a proxy, gateway, or self-hosted compatible endpoint.

let moonshotai = Moonshotai::<KimiK20711Preview>::builder()
    .base_url("https://api.moonshot.ai/v1")
    .build()?;

Path (Full URL Override)

Use .path(...) to override the full request URL instead of only the base URL.

let moonshotai = Moonshotai::<KimiK20711Preview>::builder()
    .path("https://full-url.example/v1/chat/completions")
    .build()?;

Provider Name

For logging, analytics, and observability.

let moonshotai = Moonshotai::<KimiK20711Preview>::builder()
    .provider_name("Moonshotai")
    .build()?;

Full Custom Configuration Example

let moonshotai = Moonshotai::<KimiK20711Preview>::builder()
    .api_key("your-api-key")
    .base_url("https://api.moonshot.ai/v1")
    .path("https://full-url.example/v1/chat/completions")
    .provider_name("Moonshotai")
    .build()?;

Dynamic Model Selection

For runtime model selection (e.g., loading models from config files), use DynamicModel:

Using model_name() Method with Default Settings

use aisdk::providers::Moonshotai;

// Specify model as a string at runtime
let moonshotai = Moonshotai::model_name("kimi-k2-0711-preview");

Using Builder Pattern with Custom Settings

use aisdk::{
    core::DynamicModel,
    providers::Moonshotai,
};

let moonshotai = Moonshotai::<DynamicModel>::builder()
	.model_name("kimi-k2-0711-preview")
	.api_key("your-api-key")
	.base_url("https://api.moonshot.ai/v1")
	.path("https://full-url.example/v1/chat/completions")
	.provider_name("Moonshotai")
	.build()?;

Warning: When using DynamicModel, model capabilities are not validated at compile time. This means there's no guarantee the model supports requested features (e.g., tool calls, structured output). For compile-time safety, use the typed methods like Moonshotai::kimi_k2_0711_preview().
